------解决方案--------------------
那个for循环加强有问题,最好能调试一下
------解决方案--------------------
for循环有问题
建议用Servlet+jsp的方式,不建议这样的方式,
Servlet获取值,然后再传给jsp
就像在Servlet中,
String name = request.getParameter("username");
request.setAttribute("name",name);
然后在jsp中只要
你的姓名:${name}
或者<%=request.getAttribute(name) %>获得也可以
------解决方案--------------------
用EL表达式比较简单呀
------解决方案--------------------
对了一个“}”
------解决方案--------------------
一开始就乱码了!
